LAWN QR ORCHARD I RRIGATOR.

SPECIFICATION forming part of Letters Fatent No. 465,207, dated December15 1891,

Application filed April 7, 1891.

To all whom it may concern:

Be it known that 1, WILLIAM A. RUssELL, of Los Angeles, in the county ofLos Angeles and State of California, have invented a new and ImprovedLawn or Orchard Irrigator, of

which the following is a full, clear, and exact description.

The invention relates to lawn-sprinklers having a revolubledischarge-head actuated by the pressure of the water.

The object of the invention is to provide a new and improvedlawn-sprinkler which is simple and durable in construction, not liableto get out of order, requires no high pressure for revolving the head,and is arranged to distribute the water quickly over the entire areacovered by the sprinkler.

The invention consists of a head made in two sections fastened togetherand mounted to turn on a fixed tapering discharge-pipe opening into thehead, the latter being provided with discharge-chambers having aninclined end formed with openings.

The invention also consists of certain parts and details andcombinations of the same, as will be hereinafter fully described, andthen pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding-parts in all the figures.

Figure 1 is a sectional side elevation of the improvement on the line wa: of Fig. 2. Fig. 2 is a sectional plan view of the same on the line yy-of Fig. 1. Fig. 3 is a side elevation of the head, with parts insection, and Fig. at is a reduced side elevation of the improvement.

The improved lawn-sprinkler is provided with a head A, made hollow andpreferably formed of two sections B and C, fitted with their open endsone upon the other, and fastened together by screws D, passing throughtongues E, projecting at the inside of the case, so that the watercontained in the easing does not come in contact with the said screws tocorrode the same. From each tongue E extends outward on the casing A achamber F, having its end F in the lower section 0 radial to the head,while the end F of the Serial No, 387,926 (No model.)

upper section is inclined rearwardly, as is B through which water isalso discharged,

the said water passing upwardly and outwardly to fall within a shortdistance from the periphery of the head A. The casing A is formed in itscenter with tapering openings fitted upon a taperingstationarydischarge-pipe G, formed with a series of open-.

ings G, opening into the interior of the head A. On the under side ofthe section 0 is formed a flange C, resting on a shoulder G formed onthe stationary discharge-pipe G, and serving to hold the head in place.The upper closed end of the discharge-pipe is formed with a screw-threadG extending above the top of the upper section B and engaged by a nut H,abutting against the top of the section B, so as to hold the casing inplace on the tapering stationary pipe G. The nut- H is screwedsufficiently tight to prevent leakage of the water between the head andthe tapering discharge-pipe G; but the nut is not screwed tight enoughto prevent an easy or free revolving of the head on its discharge-pipe.The discharge-pipe G is screwed or otherwise fastened on the upper endof an elbow I, provided with a flange J, secured be- 1 tween the frontends of two runners L, adapted to be moved about on the lawn to besprlnkled.

The lower end of the elbow I is formed with a screw-thread K, adapted tobe engaged by a coupling held on the hose N, connected with thewater-supply. By pulling on the hose N the runners are readily movedover the grass of the lawn.

The device is used as follows: Water is forced through the elbowI intothe dischargepipe G, from which the water passes through the openings Ginto the interior of the head A. The Water isforced past the tongues Einto the several chambers F, from which thewater passes to the outsidethrough the openings F in the inclined end F of the chamber F of theuppermost section B. The water i of the water entering the head A.

passing out through the openings F exerts a tangential back-pressure onthe head A, so that the latter is revolved on the taperingdischarge-pipe G in the direction of the arrow a. The water dischargedthrough the openings F is thrown a suitable distance from the sprinkler,according to the pressure The water discharged through the openings B inthe top of the upper section B falls within the water discharged throughthe openings F and the periphery of the head A, so that the entire areacovered by the sprinkler receives an equal spraying of water.

Having thus fully described'my invention, I claim as new and desire tosecure by Letters Patent 1. In a lawnI-sprinkler, a centrally-aperturedhead forrned with a series of internal chambers F, having the upperportions of their end walls inclined upward and rearward, as

shown at F andtprovided with-apertures F 'sections together, and theoutwardly-inclined apertures B in the central portion of the-uppersection, substantially as set/forth.
